A model of human visual perception of collisions is presented, based on twodimensional
measures of eccentricity and separation. The model is validated by
performing psychophysical experiments. We demonstrate the feasibility of using this
model as the basis for perceptual scheduling of interruptible collision detection in a realtime
animation of large numbers of visually homogeneous objects. The user's point of
fixation may be either tracked or estimated. By using a priority queue scheduling
algorithm, perceived collision inaccuracy was approximately halved. The ideas presented
are applicable to other tasks where the processing of fine detail leads to a computational
